DEIPYRUS.—ZAGLYPTUS. 339 
Seven specimens, not exhibiting any perceptible sexual marks of distinction. This 
species somewhat resembles Chryasus cavernosus, but it is strongly setose, the femora 
are unarmed, the tarsal claws are long and divergent, the head is almost impunctate, 
&c. The elytra are sculptured as in Pseudorhianus compressirostris, and the humeri 
are rounded externally and oblique in front.

Calandrinus, Leconte, Proc. Am. Phil. Soc. xv. p. 8305 (1876) ; Casey, Ann. N. York Acad. Sci. vi. 
pp. 468, 617. 
Casey refers three species from Colorado and New Mexico to this genus, the type 
of which is C. grandicollis, Lec., the latter apparently extending into our region. 
The tarsal structure is peculiar, approaching that of Zaglyptus.

There is a rather worn specimen of this insect in the Fry collection labelled as 
from “ Mexico.” An example from Colorado is figured. 
ZAGLYPTUS. 
Zaglyptus, Leconte, Proc. Am. Phil. Soc. xv. p. 317 (1876); Casey, Ann. N. York Acad. Sci. vi. 
pp. 468, 663. 
Of this peculiar genus two species are known, and four others are now added from 
within our limits, all of them apparently being rare. They are minute, convex, 
rhomboidal forms, with the third tarsal joint narrow (and not bilobed) and the body 
clothed with very long, scattered, bristly hairs. Zaglyptus (like Microhyus, amongst 
the Cryptorrhynchids) extends southward from the United States to Panama. The 
four Central-American forms may be grouped thus :— 
Rostrum stout, arcuate; elytral interstices narrow, costate ; body ferruginous . costatus. 
Rostrum more slender and less curved. 
Body black, the elytra rufescent or piceous ; elytral interstices broader than the 
strie, feebly convex. «1 ee ee ee te ee ew ew Crispus.
